Vaginal Dinoprostone Prior to Diagnostic Office Hysteroscopy in Postmenopausal Patients

Vaginal Dinoprostone Prior to Diagnostic Office Hysteroscopy in Postmenopausal Patients: A Randomized Double-Blind Placebo-Controlled Trial

To compare the effectiveness of vaginal dinoprostone with placebo in minimising the pain experienced by postmenopausal patients during diagnostic office hysteroscopy and to assess the ease of insertion of hysteroscope as reported by the hysteroscopist.

Study Overview

• Status: Completed
• Conditions: Office Hysteroscopy
• Intervention / Treatment: Drug: Dinoprostone 3Mg Vaginal Tablet; Drug: placebo vaginal tablet

Detailed Description

hysteroscopy is commonly used in the diagnosis and treatment of intrauterine lesions such as polyps, fibroids, septa, and adhesions, and in the presence of abnormal bleeding and during the removal of an intrauterine device or foreign body.Cervical ripening is made possible by the use of medication through different routes.The most commonly used agent is misoprostol,a synthetic prostaglandin E1 (PGE1) analogue that is frequently administered in off-label use in obstetrics and gynaecology for medical abortion, labor induction, endometrial biopsy, dilatation and curettage, intrauterine device insertion, myomectomy, postpartum haemorrhage, and cervical ripening.In contrast, dinoprostone, a natural PGE2, is mostly used in obstetrics for cervical ripening and the stimulation of uterine contractions to induce labor.
